Narrative:
It was my first day of IOE with a regional airline. It was the captain's leg. We were given a descent and altimeter setting. The captain set the wrong numbers in his altimeter. He was off by 1 inch. The captain failed to call for the 'descent and approach' check which would have caught the mistake. I failed to catch his mistake or prompt him for the checklist. We descended 1000 ft too low as the altitude alerter was connected to the captain's altimeter. I had also missed (possibly) my 1000 ft to level off call. ATC pointed out our mistake. There was no other traffic in the immediate area.

Title: FLC OF LTT ACR OP MISSETS ALTIMETER AND HAS 1000 FT ALTDEV. ATC CONTACTS THE CREW.
Narrative: IT WAS MY FIRST DAY OF IOE WITH A REGIONAL AIRLINE. IT WAS THE CAPT'S LEG. WE WERE GIVEN A DSCNT AND ALTIMETER SETTING. THE CAPT SET THE WRONG NUMBERS IN HIS ALTIMETER. HE WAS OFF BY 1 INCH. THE CAPT FAILED TO CALL FOR THE 'DSCNT AND APCH' CHK WHICH WOULD HAVE CAUGHT THE MISTAKE. I FAILED TO CATCH HIS MISTAKE OR PROMPT HIM FOR THE CHKLIST. WE DSNDED 1000 FT TOO LOW AS THE ALT ALERTER WAS CONNECTED TO THE CAPT'S ALTIMETER. I HAD ALSO MISSED (POSSIBLY) MY 1000 FT TO LEVEL OFF CALL. ATC POINTED OUT OUR MISTAKE. THERE WAS NO OTHER TFC IN THE IMMEDIATE AREA.
